IMPROVEMENT IN SELF-ACTING TEMPLES FOR LOOMS.

Specication forming part of Letters Patent No. 1,080, dated February 18,1839; antedated November 6, 18?(8,

To all whom z5 may concern:

Be it known that I, KENDALL GIBBs, of South Berwick, in the county ofYork and State of Maine, have inventeda new and useful Improvement onSelf-Adjusting Temples for Power or Hand Looms; and I do hereby declarethat the following is a Jfull and exact description.

The nature of myinvention consists in constructing the temples with ajoint, so that if the shuttle stops between the temple and the reed thetemple will be pressed back by the shuttle as the lathe strikes againstthe cloth, without injury to the shuttle, temple, or reed. This jointalso allows the temple to vibrate toward the reed as it opens, and afterit shuts, as the lathe leaves it, itvibrates from the reed with areacting motion, which makes the sel- Vage, or threads at and near theedge, tightto any degree that the operator may require, therebyfacilitating the entrance and exit of the shuttle.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

It is represented in the three accompanying drawings, of which No. l isa perspective drawing, referred to in this specification by letters. No.2 is adrawing of aside View, and No. 3 is a drawing of a top view. Thetwo last-named drawings are referred to in this specification byfigures, and the parts that are shown in both are marked or referred toin each drawing by the same gure, and the parts that are shown only inone are marked in that drawing only.

A and l (of the accompanying' drawings) is a metal stand, one part ofwhich is at right angles to the other. The upright part has two groovesor slots B B for the bolts that fasten it to the breast-beam ot' theloom, so as to raise or lower it. The lower part of the stand projectsout from the breast-beam and has a groove or slot through itlengthwise,(see Fig. 2,) through which the bolt O and 3 passes to hold the slide Dand 4, which has a slot in it at right angles to that in the stand, sothat the operator can set the temple near or far from the breast-beam intoward the cloth or out from it.4 The slide D and 4 has two projectionsupon the end, as E E and 5 5, which have the pin F and (5 passingthrough them and the lower end of the main part of the temple G and 7,which forms the joint, upon which it vibrates easily. The main part ofthe temple G and 7 has a crooked arm projecting from it, as at H and S.This arm has -a straight projection from it, as at I and 9,

which forms the upper jaw of the temple. The upright portion of the mainpart G and 7 has al perpendicular groove through its whole length, fromone side of which the crooked arm II and 8 projects. There is an angularlever K and 10 fastened in this perpendicular groove by a pin L and ll,upon which it moves easily. The arm M and 120i' this angular lever has apiece across the end N N and 13,13, which forms the lower jaw of thetemple. This lower jaw has teeth in it, so as to hold the cloth firmly.The arm O and 14E (which is in the perpendicular groove) has aprojection vupon the lower end IJ and l5, against which the head of thescrew (that is screwed into the race-board of the lathe ot the loom)strikes to open the jaws of the temple when t-he lathe strikes againstthe cloth. The jaws are shut by the spring 10, the upper end of which isriveted or dovetailed into the perpendicular groove behind the angularlever K and l0, and the lower end stands out against the arm O and 14 ofthe lever K and 10 and shuts the temple firmly. In the Drawing No. 2 theside of the main part Gr and 7 and one side of the slide D and 4 areleft off to show the lever K and l0 and the spring 16. The slide D and 4has a projection on the un-- der side Q and 17, with a hole drilled intoit for the spiral spring R and 1S, that acts against the lower end S and19 of the main part G and l0, and presses it out, throwing the jaws fromthe reed, which draws the selvage or threads at and near the edge,tight. (In Drawing No. 2 a part of the projection Q and 17 is left oftto show the spiral spring R Iand 18.) As the lathe strikes against thecloth the head of the screw in the race-board hits the projection P andl5, which is below the pin F and 6, and as the spiral spring R and 1S ispressed back with less force than the spring 16 behind the lever K andl0 in the per- 2 Lose pendieular groove it throws the jaws toward thereed until the part S and 19 presses in the spring R and 18 and stopsagainst the projection Q and 17, when the end of the lever P and l5 ispressed back into the groove and opens the jaws for the eloth to bedrawn through. As the lathe leaves the temple it removes the pressurefrom the projection P and 15, and as the spring that shuts the jaws isstiffer than the other the jaws are shut before the spiral spring R and18 aets to throw the temple from the reed. After the temple is shut, asthe lathe leaves the temple the spiral spring ae ts and throws thetemple from the reed, Whieh draws the selvage or threads at and near theedge of the web tight. The lastnamed threads being drawn tight makes theharness open the shades of yarn or silk with more certainty andfacilitates the entrance and exit of the shuttle, and it' the shuttlestops between the temple and the reed as the lathe strikes up againstthe cloth, the shuttle strikes the jaws of the temple, and as the templeis hung upon a joint, of which the pin F and 6 is the fulerum, theshuttle, striking against the jaws of the temple, presses or throws themback toward the breast-beam without injury to the shuttle, temple, orreed.

Vhat do claim as my invention, and desire to seeure by Letters Patent,is-

1. The joint that allows the jaws of the temple to vibrate toward thereed before they open and from the reed after they are shut, and furtherallows the temple to be pressed back by the shuttle when it stopsbetween the temple and the reed Without 'injury to the shuttle, temple,or reed.

2. Making the projection upon the lever that opens the temple on theopposite side of the fulerum or joint from the jaws, so that the jawsare thrown toward the reed before they open and from the reed after theyare shut.

3. Making the spring that shuts the temple stiffer than the one thatthrows the jaws of the temple from the reed, so that the jaws are throwntoward the reed before they open and from the reed after they are shutto draw the selvageer threads at and near the edge tight, the wholebeing constructed and operating as herein described.
